"I had a great experience with them. Their bid was right in the middle where it should have been. The guy who showed up had estimated for 5-6 hours worth of work, and he ended up staying here for almost 9 hours, but they didn't charge me extra for it, and I was happy about that. He was able to run the wiring where I wanted it to run. There weren't all the cables showing and he was able to stick it through my wall, and that is why he ended up staying here for so long. I was really happy with the service. My biggest thing was that the guy stayed until the work was done, he didn't say he would come tomorrow even if it meant working overtime."
